Predicted difficulty with enforcement is one of the reasons several porn industry officials have already condemned the move, calling it an unneeded exercise that will bankrupt the San Fernando Valley - the nation's Porn Capital.

"You can't actually compel an industry to create a product that the market doesn't want," said Christian Mann, general manager of Evil Angel Productions, one of the industry's biggest makers of porn films. He says that many audiences simply won't pay for films with condoms.

The law represents a major victory for the AIDS Healthcare Foundation, which has made condom use in pornography one of its flagship issues.
